Answer:
39.5
Explanation:
We will solve according to order of operations.
7 × 3 + [ 6 + 2 × (23 ÷ 4 + 3 × 2) – 7 × √4 ] + 9 ÷ 3
We must solve the innermost parentheses first. We must do the division first.
7 × 3 + [ 6 + 2 × (5.75 + 3 × 2) – 7 × √4 ] + 9 ÷ 3
Next is the multiplication in the innermost parentheses.
7 × 3 + [ 6 + 2 × (5.75 + 6) – 7 × √4 ] + 9 ÷ 3
Next is the addition in the innermost parentheses.
7 × 3 + [ 6 + 2 × (11.75) – 7 × √4 ] + 9 ÷ 3
We can remove the parentheses here.
7 × 3 + [ 6 + 2 × 11.75 – 7 × √4 ] + 9 ÷ 3
We must now do the square root in the brackets, as it takes precedence.
7 × 3 + [ 6 + 2 × 11.75 – 7 × 2 ] + 9 ÷ 3
Now for the multiplication in the brackets.
7 × 3 + [ 6 + 23.5 – 7 × 2 ] + 9 ÷ 3
Now for the multiplication in the brackets.
7 × 3 + [ 6 + 23.5 – 14 ] + 9 ÷ 3
Now addition in the brackets.
7 × 3 + [ 29.5 – 14 ] + 9 ÷ 3
Now subtraction in the brackets.
7 × 3 + [ 15.5 ] + 9 ÷ 3
We can remove the brackets here.
7 × 3 + 15.5 + 9 ÷ 3
Now for the multiplication.
21 + 15.5 + 9 ÷ 3
Now for the division
21 + 15.5 + 3
Now for the addition.
21 + 15.5 + 3
39.5
Therfore, 39.5 is your final answer.
